Ahmed Seffah is a professor in the department of Computer Science at Concordia University. He is director of the Human-Centered Software Engineering Group and the co-founder of the Concordia Software Usability and Empirical Studies Lab. He holds a PhD in software engineering from the Ecole Centrale de Lyon (France). His  research interest are at the crossroads between software engineering and Human-Computer Interaction (HCI), including usability measurement, user interface design, empirical studies on developer experiences with CASE tools, human-centered software engineering, and patterns as a vehicle for integrating HCI knowledge in software engineering practices. Dr. Seffah  is the vice-chair of the IFIP  working group on user-centered design methodologies. During the last 10 years, he has been involved in different projects in North America and Europe.

Homa Javahery is a researcher and project manager with the Human-Centered Software Engineering Group, including the Usability and Empirical Studies Lab, in the department of Computer Science at Concordia University. She holds a Master's degree in Computer Science from Concordia University, and a Bachelor of Science degree from McGill University. She is combining different design approaches from human sconces and engineering disciplines to develop a pattern-oriented framework for designing a large variety of interfaces. She has been involved in different collaborative projects at the INRIA Research Institute in Nancy, France and the Daimler-Chrysler Research Institute in Ulm, Germany.
